Crimea

Crimea is a peninsula located on the Black Sea, in either southeastern Ukraine or southwestern Russia (it has been disputed since March 2014). The Crimea was annexed by the Russian Empire in 1783, and it would become a part of the Russian SFSR after the October Revolution of 1918. However, it would be transferred to the Ukrainian SSR in 1954, and Crimea remained a part of Ukraine until March 2014, when unmarked Russian Army troops, local cossacks, and Russian sympathizers took over the Crimea from the Ukrainian Army.
